    Description

      Most likely after QSerialPort: Port to alertable I/O functions on Windows (Idc428173) - Gerrit Code Review (qt-project.org) we received a lot of regression reports about data loss, read/ write delay on Windows. A possible solution to this problem is to partially rewrite the above implementation using Allow QWindowsPipe(Reader|Writer) to work with foreign event loops
